.To all whom it may concern.s

Be it known that we, JOHN WILSON and ALLAN MASON, citizens of the United States, and residents of New York city, in the county and State of New York, and Brooklyn, Kings county, NewYork, respectively, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification. v

Our invention is an improved contrivance of hydrocarbon-injector burners for regulating the oil-supply in marine-boiler furnaces, where the rolling of the ship causes irregularity of the iiow in the feed-pipe, all as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure 1 represents a sectional elevation of our improved injector, as when the ship is in the normal position. Fig. 2 is a section of the oil-feed regulator, as when the ship is in the same position. Fig. 3 is a section of the regulator, as when the injector has a descending inclination by the roll of the ship. Fig. 4 is a section of the regulator, as when the injector has an upward inclination by the roll of the ship, and Fig. 5 is a sectional elevation of a marine boiler having our improved burner applied to it.

The oil, steam, and air are mixed or combined in a mixing-chamber or casing a prior to entering the furnace, said mixing-chamber consisting ofthe tube inserted about midway of its length or a little more in the fire-door or furnace-plate m, and having its ends open and curved upwardly; also, having the oil-feed pipe b discharging into it through the bottom and outside of the furnace, and also having the steam-nozzle d introduced a certain distance from the outer end, as shown, whereby the oil from the oil-feed pipe b is combined with the air entering the chamber at cby the effect of the steam-jet from the nozzle d for combustion at the issue e in the furnacechamber. This mixing-chamber stands level when the ship is level; but by the rolling of the ship it sometimes has a downward pitch, as in Fig. 3, which accelerates the flow of the oil and causes an over-supply, and at other times it has an upward pitch, as in Fig. 4, which retards the iiow and prevents the supply of the requisite quantity at the burner,

while the steam-jet and air injected by it continue the same, thus materially interfering with eifective and economical combustion.

To remedy this evil we provide the oilfeed pipe with a regulating-cock f, having a pendulum regulator g for automatically shifting it, which cock and pendulum are so adj usted that they partly close the passage h to regulate the supply when the mixing-chamber stands level, as in Figs. 1 and 2, and close it still more when the pitch of the chamber is downward, as in Fig. 3, but open it wider when the pitch is upward, as in Fig. 4, thus eecting automatic regulation according as the ship rolls.

The chamber is constructed with an upward curve of the outer end to prevent the outflow of any oil that may possibly fail of being drawn inward by the suction of the jet when the pitch of the injector is upward, and the inner end is also made with an upward turn as a further means of limiting the iiow when the pitch is downward, and also with cross-ribs or bars fi, and pockets j, along the bottom of the interior for the lodgment of any unvaporized portions for obstruction and retention till effectually broken into spray by the jet. The bottom is also perforated with numerous small orifices lo along the curve and between the cross-ribs for a further means of causing the scattering of the atoms in spray, and for the issue in divisional jets into the atmosphere of the place of combustion.

m represents the door or front plate of the furnace,through which theinj ector is inserted.

What We claim, and desire to secure by Letters Patent, is

1.l The combination,with the furnacechamber, of the mixing-chamber havingboth ends open and upwardly curved to prevent outiiow of oil when out of level by the pitch of the vessel, and extending into the furnacechamber through the front of the same, the oil-supply pipe connected with said mixingchamber, and the steam-j et pipe entering said outwardly-curved open end and projecting the steam against the inner surface of the upwardly-curved bottom of the inner end of said mixing-chamber, substantially as described.

2. The combination, with the furnace-cham- IOO ber, of the mixing-chamber, having both ends open and upwardly curved to prevent the outflow of oil when out of level by the pitch of the vessel, and extending into the furnacechamber through the front of the same, the oil-supply pipe connected with said mixingchamber, the regulating-cock in the oil-pipe, the pendulum actuator of the regulatingcock, and the steam-nozzle inserted in the outer open end of the mixing-chamber, and projecting the steam against the inner surface of the upwardly-curved bottom of the inner end of said mixing-chain ber, substantially as described.

3. The combination, with the f urnace-chaniber, of the mixing-chamber having both ends open and. upwardly curved to prevent outioW of oil when out of levelV by the pitch of the Witnesses:
